The benefits of using the Y chromosome in genetic genealogy are often not well understood. Please consider that with Big Y and Y111 and in the future, Y500, this has all changed. Y DNA is a powerful, reliable family lineage tracker, from genealogy to the ancient. Since every woman has a father the Y can track up to half of all lineages. It also has a nice affinity to surnames, land and other legal records.
Y DNA is extremely high resolution and useful in the genealogical timeframe. At the same time it does not wash out like autosomal DNA so Y DNA can break through genealogical brick walls.|
